  • Patent number: 11226319
    Abstract: A method of use encompassing coded sampling containers that may be implemented in two phases, the results of which may be further processed to arrive at a final score. The first phase incorporates four sampling containers in the context of a series of triangle tests to arrive at a first subscore. The second phase uses two of the coded containers and requires the participants to assess the degree to which the contents of the containers reflect a particular characteristic on a scale. The responses of each participant may be scored by summing the differences between the actual answers and the correct answers to arrive as a second subscore. A final score may be calculated by subtracting the first subscore from the second subscore.

MS/MS analysis is performed for each selected m/z segment, using ions whose m/z values fall within the m/z segment as precursor ions. A measurement cycle which includes mass spectrometric analysis performed one time and MS/MS analysis performed one or more times is repeated. After that, ions originating from the same component are selected based on the retention time of a peak in an extracted ion chromatogram created for each product ion, and the component is identified.

  • Patent number: 10060942
    Abstract: Systems and methods for measuring turbulent gas flux using high-speed vertical wind speed measurements (e.g., on the order of 5-10 Hz or more frequently) and low-speed gas content measurements (e.g., on the order of 5 Hz or less frequently), without the need for the sophisticated and expensive high-speed hardware to separate gas samples (e.g., into accumulation bags) according to updrafts and downdrafts. A time series of high-speed vertical wind speed data is used as a guide to distinguish between updrafts and downdrafts. When vertical wind speed is upward (updraft), the low-speed gas content is recorded into a data structure in one location, or marked with one flag. When vertical wind speed is downward (downdraft), the low-speed gas content is recorded into a different location, or marked with a different flag. Eddy Accumulation or Relaxed Eddy Accumulation computations can be performed using the stored gas content data to determine gas flux.

  • Patent number: 10001462
    Abstract: A method and system for detecting pesticide residue in agricultural products. The system includes a chromatographic and mass-spectrometric system and a computer. The system inspects first and second sample solutions prepared from two identical extracts of an agricultural product. The first sample solution includes no additives while the second sample is added with a pesticide standard which is intended to be detected by the system for comparison. The computer compares the mass chromatograms of the first and second sample solutions, and calculate an increased integral area by which the peak of the second sample solution in the second mass chromatogram exceeds the peak of the first sample solution in the first mass chromatogram at the same retention time. As such, the concentration of pesticide residue in the sample can be determined by a ratio between the increased integral area and the concentration of the pesticide standard.

  • Patent number: 9976997
    Abstract: When there are a plurality of concentration value candidates, an extreme value of the calibration curve is detected, and the number of calibration points respectively contained in a region having a low concentration and a region having a high concentration is calculated using the extreme value as a boundary. If there is a difference between the numbers of calibration points of both regions, a concentration value candidate present in the region having a larger number of calibration points is selected as a quantitation result. When the numbers of calibration points are the same, the sign of the coefficient of the term of the second degree of the calibration curve is assessed, and a concentration value candidate present in a region in which the relationship between peak area values and concentration values is monotonically increasing is selected as a quantitation result.

  • Patent number: 9733214
    Abstract: MRM triggered MRM, where the triggered MRM transitions make use of mobility device parameter values for the same compound, is performed. A plurality of primary MRM transitions are received and stored together with a mobility device parameter value for each transition as an MRM cycle list. Control information instructs a mobility device and a mass spectrometer to interrogate each MRM transition on the MRM cycle list within an MRM cycle of the mass spectrometer. If a product ion intensity value of an MRM transition exceeds a threshold value for a primary MRM transition, a plurality of secondary MRM transitions of the primary MRM transition with different mobility device parameter values are added to the MRM cycle list. The intensities of the measured secondary MRM transitions provide information on the optimum mobility device parameter for each compound.

  • Patent number: 9431224
    Abstract: When performing an automatic MS2 analysis on a specimen containing components that include elements whose abundance ratio of stable isotopes is close, to prevent the same component that includes isotopes of differing masses to be successively selected as a precursor ion and allow the MS2 analysis of various components whose retention time to elution is close. As precursor selection conditions, the user is allowed to set in advance the time period for automatic exclusion and a m/z range (?p, q) with respect to any m/z. When the analysis is performed, a precursor selection unit selects a precursor according to a predetermined selection condition for the MS spectrum that was obtained and repeats the MS2 analysis on the precursor ion (m/z=M) for the number of times that is set. Thereafter, for a specified automatic exclusion period, ions falling in a m/z range of M?p to M+q are excluded from selection as a precursor.

  • Patent number: 9280516
    Abstract: The present invention provides a method and system using wireless sensors to validate wired sensors used in applications where the requirements on the reliability of wired sensors are stringent. A computing means periodically collects measurements for each variable from the wired and wireless sensors and compares them against an expected value. The expected value is a weighted average of all the measurements for a variable, in which the weight assigned to the measurement from each sensor is determined according to both its reliability and accuracy. As such, measurements are compared with the corresponding expected value for a particular variable. If the difference between a measurement and its corresponding expected value is found to be unacceptable, the validation computer will generate a corresponding alert. Application examples include 1) validating wired sensors used in safety shutdown systems for industrial facilities and 2) validating wired sensors used to monitor storage tanks.

  • Patent number: 9140677
    Abstract: In exemplary implementations of this invention, an electronic olfactor determines whether a scent being tested matches the scent of a positive control. The electronic olfactor can perform this scent matching even in a changing olfactory environment, and even if the positive control scent is a combination of hundreds or thousands of different odorants. No prior training is needed, and no attempt is made to identify a single odorant that is unambiguously responsible for a scent. Instead, a computer compares the total scent pattern of a positive control sample with the total scent pattern of a test sample, across a sweep of many permutations of electrical inputs to scent sensors, to try to find any condition under which the total scent patterns do not match. If such a condition cannot be found, then the computer declares a match between the test and target scents.
